HTML Table 固定列宽，实现excel表格效果

(1)获取行号

<table>
<tr onmouseover ="showIndex(this)"><td>1</td></tr>
<tr onmouseover ="showIndex(this)"><td>2</td></tr>
<tr onmouseover ="showIndex(this)"><td>3</td></tr>
<tr onmouseover ="showIndex(this)"><td>4</td></tr>
</table>
function showIndex(pVal) {
    alert(pVal.rowIndex);
}

 

 (2)改变颜色、符号

    /*在行上改变 图片*/
   for(var i=0;i<=pTable.rows.length-1;i++)
    {
        var row=pTable.rows[i];
        row.onmouseover = function() {/*js this是事件的触发者*/
        this.style.backgroundColor="#ffff00";
        var tempDv = this.childNodes[0].childNodes[0];
        var currentY = parseInt(tempDv.style.backgroundPositionY.split('px')[0]);
        var newY = currentY - 30 + "px";
        tempDv.style.backgroundPositionY = newY;
        }
    
        row.onmouseout = function() {
             this.style.backgroundColor="#ffffff";
            var tempDv = this.childNodes[0].childNodes[0];
            var currentY = parseInt(tempDv.style.backgroundPositionY.split('px')[0]);
            var newY = currentY + 30 + "px";
            tempDv.style.backgroundPositionY = newY;
        }
    }
